The fight eventually moved into a bathroom. The woman claims gill filled the tub up with water, threw in her clothes, poured bleach on them and then threw her in.

"Yeah, I wouldn't say this is murder by bleach, but it is a warrant out for strangulation, this is something different, this is something in the course of my career I haven't seen yet."

According to court documents, the woman and gill continued to fight in her car, where she was thrown out and he drove off.

APD Detectives asked marshals for help for two reasons. Gill is from Tennessee; he may have fled there and he also has a very violent past.
